Methanol extraction determined higher levels of carotene pigment in tomatoes,varying between 3.39 mg/100 g and 20.52 mg/100 g in fresh product, in pepper the concentrations of carotene were between 2.59 mg/100 g and 42.83 mg/100 g in fresh product,and in cucumbers the concentrations obtained ranged from 18.13 mg/100 g and 33.86 mg/100g fresh product. In the third extracting solution – acetone, the obtained carotene values were higher,thus in tomatoes were between 2.99 mg/100 g and 54.78 mg/100 g fresh product, in peppers between 11.95 mg/100 g and 74.70 mg/100 g fresh product, and in cucumbers the concentrations ranged from 13.94 mg/100 g fresh product and 27.49 mg/100 g fresh product (Table 1). Comparing the results of the three extractions of carotene, acetone extraction determined the best results in all analyzed vegetables: tomatoes, peppers and cucumbers. Statistical interpretation of results of carotene showed that acetone extraction resulted in the best variation coefficient respectively 70.4% at cherry tomatoes, 11.77% at common tomatoes, 91.27% at peppers and 24.18% at cucumbers. Methanol extraction also showed coefficient of variation of the results slightly lower than for acetone extraction, respectively 54.31% for cherry tomatoes, 16.25% for common tomatoes, 90.27% for peppers and 16.55% for cucumbers (Table 2). |

甲醇提取可确定每100克新鲜西红柿中含较好的胡萝卜素3.39毫克到20.52毫克，新鲜辣椒中胡萝卜素含量为2.59毫克到42.83毫克，在新鲜黄瓜中的含量则介于18.13毫克至33.86毫克之间。 在第三种提取液 - 丙酮中所获得的胡萝卜素值均较高，因此，丙酮提取每100克新鲜西红柿中含2.99毫克到54.78毫克，新鲜辣椒中11.95毫克到74.70毫克，在新鲜黄瓜中13.94毫克到27.49毫克（表1） 。 比较三种胡萝卜素提取方法所得结果，丙酮提取法在分析的蔬菜：西红柿，辣椒和黄瓜中均取得了最佳的结果。胡萝卜素提取数据结果表明，丙酮提取最好的变化系数分别为樱桃西红柿70.4％ ，普通西红柿11.77 ％，辣椒91.27％ ，黄瓜 24.18％。甲醇提取系数的变化的结果略低于丙酮提取，樱桃西红柿为54.31％ ，普通西红柿 16.25 ％，辣椒90.27％，黄瓜16.55％（见表2） 。 “variation coefficient”这词我没多少把握，其他的看着用吧。供参考。 |
